Collected from an unknown hoard in 2020, and not common in the wild. Its two dential processes differ from other Toxodentids, as they form two inward-pointing triangles. No data is yet known about its life habits or host entities. C. viperulus is thought to be endemic to Australia, a continent where many species are famous for their powerful venom. Although all specimens handled were generally docile,  fingers should be kept out of its oral groove, just in case. Species discovered and submitted by occlupanologist-artisan S. Nottingham.
